摘要：

Sampling height-age errors in tree-ring dating are estimated by extrapolation of mean apical growth rates for 188 Engelmann spruce growing in four glacier forefields in the southern Canadian Cordillera. Average correction factors obtained are 1 to 4 yr for sampling heights of 10 cm and 6 to 19 yr for sampling heights of 50 cm. These data suggest sampling height is a relatively minor source of error in the determination of tree age in glacier forefields if the trees are sampled within 10 cm of the root crown.
